Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a copper sleeve heater. Background Art

[0002] In order to prevent the plastic melt from solidifying in the injection nozzle, the injection nozzle of the existing injection mold is generally equipped with a corresponding heating device, mainly a copper sleeve heater and a spring heating coil.

[0003] Among them, patent number ZL 201320019231.8, entitled "A Chinese Utility Model Patent for a Temperature Measurement Structure of a Tubular Heater," discloses an open copper sleeve heater comprising a copper sleeve, a heating wire, and a thermocouple probe. The copper sleeve is provided with a sleeve hole, a notch, a wiring slot, and a probe placement slot. The wiring slot is densely distributed at both ends and sparsely distributed in the middle. The heating wire is embedded in the wiring slot, and the thermocouple probe is embedded in the probe placement slot. The heating wire and the wiring slot are in close contact over a large area, allowing heat generated by the heating wire to be quickly transferred to the copper sleeve. The heating wire is distributed densely at both ends along the wiring slot, sparsely distributed in the middle, thereby compensating for heat loss from the injection molding nozzle and achieving thermal balance. The notch is elastically openable and closable, making assembly and disassembly easy, and the sleeve hole fits tightly against the injection molding nozzle, resulting in high thermal conductivity. The thermocouple probe is embedded in the probe placement slot, reducing the need for corresponding fixings and installation space, and preventing damage to the thermocouple probe due to exposure.

[0004] It should be pointed out that for the above-mentioned open copper sleeve heater, a probe placement groove is set on the surface of the copper sleeve, and its probe head must be installed at one end of the copper sleeve, so the temperature can only be measured at one end of the injection hot nozzle.

[0005] In addition, the Chinese utility model patent with patent number ZL202223203509.5, entitled "An Open Copper Sleeve Heater," discloses a temperature measurement structure for a tubular heater, comprising a tubular heater body, a vertically arranged through slot provided at the upper end of the inner wall of the heater body, and a U-shaped upper notch and a lower notch provided at each end of the through slot, a probe locking screw hole provided at the lower end of the upper notch, and the probe locking screw hole extends through the upper end of the through slot, a heater locking screw hole provided at the upper end of the tube wall opposite to the through slot provided with the heater body, a vertically arranged groove provided at the upper end of the surface provided with the through slot provided with the heater body, and a compression screw hole provided at the side end of the groove. The utility model uses a screw in the probe locking screw hole to lock the probe head of the temperature sensing probe to the surface of the injection molding nozzle; therefore, the utility model has the advantages of novel design, simple structure, easy installation, accurate temperature measurement, no need to groove the upper end of the injection molding nozzle surface, thereby increasing the service life of the injection molding nozzle, improving production efficiency, and reducing production costs.

[0006] It should be pointed out that, for the temperature measurement structure of the above tubular heater, a through slot for placing a thermocouple probe is provided on the upper end of the inner wall of the heater body. The heater body is difficult to process, has high production costs, and is not easy to install. Utility Model Content

[0007] The purpose of the utility model is to provide a copper sleeve heater to address the deficiencies of the existing technology. The copper sleeve heater has a novel design, a simple structure, is easy to process and has a low production cost. It is easy to install, and the probe head can be installed at any position in the through slot for easy temperature measurement.

[0008] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions.

[0009] A copper sleeve heater comprises a copper sleeve body. A vertical through groove is provided at the upper end of the copper sleeve body and passes through the inner and outer walls of the copper sleeve body. A U-shaped guide opening is provided at the lower end of the through groove.

[0010] Among them, a plurality of threaded heating wire wiring grooves are provided on the upper end of the surface of the copper sleeve body.

[0011] Wherein, the width of the through groove is greater than the diameter of the thermocouple probe.

[0012] Wherein, the through groove does not penetrate or penetrates the top of the copper sleeve body.

[0013] The beneficial effects of the present invention are as follows: the copper sleeve heater described in the present invention comprises a copper sleeve body, a vertically arranged through groove is provided at the upper end of the copper sleeve body, and the through groove penetrates the inner and outer walls of the copper sleeve body, and a U-shaped guide opening is provided at the lower end of the through groove.
